..Soggy end to May over southern Manitoba..

A slow moving storm system over the Dakotas brought another round of heavy rainfall to southern Mnaitoba over the past two days, less than 2 weeks after a similar rainfall event brought drenching rains to the same area over the Victoria Day weekend. General rainfall amounts of 30 to 60 mm were widespread mainly along and south of the TransCanada highway with locally heavier amounts of 80 to 125 mm along the western Red River valley. At my site in Charleswood, I recorded a storm rainfall total of 43 mm, while 50 to 70 mm was reported over the south end of the city. La Salle reported 54 mm. Unofficial reports of 80 to 125 mm were received for areas along the western Red River valley from the Austin and MacGregor areas to west of Miami to the US border. Overland flooding was once again reported in the Morden area due to heavy rains along the Pembina escarpment. This area was flooded over the Victoria day weekend as well with local amounts of 100 to 200 mm of rain during the 3 day rainfall event. Rainfall storm totals to 1 am Saturday since the rain began Thursday morning..
